2. ELECTRICAL SUPPLY INSTALLATION.
The electrical installation of the equipment making up the system must be carried out by specialised personnel accord-
ing to the applicable standards. The location must fulfil the following conditions:
Place: Dry and ventilated, far enough away from the welding area in order to prevent the metal dust caused by the
welding process from getting into the equipment. The equipment must not be used in the rain.
PLACE THE WELDING MACHINE ON A FIRM FLAT SURFACE. IF EQUIPMENT OF THIS KIND TIPS
OVER IT CAN HAVE VERY SERIOUS CONSEQUENCES.
The main switchboard where the machine has to be connected must be comprised of a differential circuit breaker and a
magnetothermal switch.
AUTOMATIC CIRCUIT BREAKER (IA): Three-pole or four-pole. The instrument will be chosen according to the character-
istics plate. We advise choosing a slow type Intensity-Time characteristic (Curve G), as false tripping could occur due to
transitory overloads.
DIFFERENTIAL CIRCUIT BREAKER (ID): Four-pole or three-pole with minimum sensitivity of 300 mA. The aim of this
switch is to protect the personnel from direct or indirect contact with electrical parts under voltage. The differential circuit
breaker is selected with a superior gauge to ID.

ELECTRICAL CONNECTION FROM POWER SOURCE TO COOLING MODULE
ATTENTION:
BEFORE STARTING THE INSTALLATION CHECK THE SUPPLY VOLTAGE THAT IS INSTALLED
THE COOLING MODULE WCS 520MV Ref.659.82.000(See manual):

On the inside of the wire feed unit volume, there is an electrical power source connection system with WCS cooling
module. Follow the operations below:
3. Remove the protection housing.
4. Carry out the connection of connector as shown in detail A. Please close then the lid.

The connection to the mains is made from the intake hose. The Figure on the left shows
the connection of the intake hose to the two most common types of standardised plug
(IEC 309-2). In this figure L1, L2 and L3 show the phase cables and PE represents the
earth protection conductor.
DO NOT FORGET TO FIT THE EARTH CONNECTION INTO THE PLUG.
